Abstract
The invention provides a foam-stabilizing reinforcing agent for chemical-foamed foam concrete. The form-stabilizing reinforcing agent comprises the following components by weight part of 80 parts of water, 20-34 parts of water-based calcium stearate, 5-10 parts of calcium chloride, 0.1-0.5 part of organosilicon water repellent, 1-2 parts of polyoxyethylene type shrinking and reducing agent and 0.1-0.5 part of hydroxypropyl methyl cellulose. The foam-stabilizing reinforcing agent has the advantages of being applicable to production of foam concrete with light weight and high strength, prolonging foam stabilizing time, improving hole structures of foam concrete, improving yield, shortening stripping time and improving early strength. In addition, the form concrete produced by the foam-stabilizing reinforcing agent is low in water adsorption, long in service life and not prone to cracking.
Description
Technical field
The present invention relates to a kind of chemical building material technical field, refer in particular to a kind of chemical foaming foamed concrete with surely steeping toughener.
Background technology
Chemical foaming foamed concrete is joined by chemical foaming agent in the slurry being made up of cement-based gelling material, adulterant, admixture, water, through mix and blend, builds, quiet stops paying out bubble, maintenance and the porous insulation material that becomes. Chemical foaming occurs chemical reaction to produce gas and foam by chemical foaming agent in the slurry. Compare physical blowing foamed concrete, the froth stability of chemical foaming foamed concrete is poor, bubble hole is thick, aperture is uneven, shape is irregular, percentage of open area height, and selecting of suds-stabilizing agent can improve chemical foaming foamed concrete pore structure well, it is to increase production yield rate.
At present, suds-stabilizing agent mainly contains macromolecular substance (polyacrylamide, polyvinyl alcohol, albumen, polypeptide, starch, Mierocrystalline cellulose etc.), silicone resin polyethers type of latex type, nonionogenic tenside, aliphatic category etc. Wherein, macromolecular substance complicated operation, gas release is low; Silicone resin polyethers type of latex type foam stabilizing effect is obvious, but synthesising different structure body is many, it is difficult to control; Nonionogenic tenside foam stabilizing effect is general, and by product and impurity many; Aliphatic category is insoluble to water, not easily stirs evenly. The foam stabilizing effect of suds-stabilizing agent and foaming system and whipping agent have much relations. Common chemical foaming foam concrete foamer is hydrogen peroxide, is mainly oxygen in bubble, and foam and air foam are different.
Chemical foaming foamed concrete is porous light-weight material, and intensity is low, and demould time is long, water-intake rate height, and easily ftractures in cutting and use procedure, and thus its application and popularization are subject to certain restrictions.
Summary of the invention
The technical problem to be solved in the present invention, is to provide a kind of chemical foaming foamed concrete with surely steeping toughener.
The present invention is achieved in that a kind of chemical foaming foamed concrete is with surely steeping toughener, comprises each component of following weight part number:
It is an advantage of the current invention that:
1) can be used for producing the foamed concrete of high-strength light, product water-intake rate is low, long service life;
2) extend the foam stabilization time, improve foamed concrete pore structure, it is to increase yield rate;
3) demould time is shortened, it is to increase early strength, and not easy to crack.
Embodiment
A kind of chemical foaming foamed concrete, with surely steeping toughener, comprises each component of following weight part number:
Described steady bubble toughener is main raw material taking water-based calcium stearate, adds a certain amount of short solidifying hardening accelerator calcium chloride, organosilicon moisture repellent, polyoxyethylene economization agent and water-holding agent composition, and water-holding agent is Vltra tears; Only above raw material need to be added in container by a certain percentage, constantly stir, fully dissolve, can use.

Produce every cubic metre of foamed concrete, add above-mentioned steady bubble toughener 1000g and evenly stir. The dry density recording finished product with reference to JG/T266 " foamed concrete " is 266kg, and ultimate compression strength is 0.97MPa, and water suction grade is W5.
Embodiment three
Take the water of 80g, the water-based calcium stearate of 34g, the calcium chloride of 7g, the organosilicon moisture repellent of 0.5g, the Vltra tears of 1g polyoxyethylene economization agent and 0.1g, in container, constantly stirs, fully dissolve, chemical foaming foamed concrete can be obtained with surely steeping toughener. Produce every cubic metre of foamed concrete, add above-mentioned steady bubble toughener 1000g and evenly stir. The dry density recording finished product with reference to JG/T266 " foamed concrete " is 261kg, and ultimate compression strength is 0.90MPa, and water suction grade is W5.
The present invention has the following advantages:
1) the present invention adopts water-based calcium stearate to be the main component surely steeping toughener, overcome the hydrophobic nature of calcium stearate powder body suds-stabilizing agent, easier Homogeneous phase mixing is mixed with slurry, shorten churning time, and the oxygen foam system adaptability that chemical foaming produces is more good, enhancing foam stabilizing effect, bubble hole is more even, it is to increase yield rate;
2) adopt calcium chloride early strength coagulant, the presetting period of slurry can be shortened, greatly improve early strength, in 6 hours, get final product the demoulding, it is to increase production efficiency;
3) organosilicon moisture repellent is adopted can effectively to solve the high shortcoming of the water-intake rate of foamed concrete;
4) adopt polyoxyethylene economization agent can reduce foamed concrete early strength and increase the too fast contraction caused, decrease later stage cracking phenomena, extend the work-ing life of foamed concrete;
5) Vltra tears water-holding agent is adopted can to reduce in production process the dry shrinkage fracture caused because of strong wind, hot weather etc.
Although the foregoing describing the specific embodiment of the present invention; but it is familiar with those skilled in the art to be to be understood that; specific embodiment described by us just explanation property; instead of the restriction for the scope to the present invention; those of ordinary skill in the art in the modification of the equivalence done according to the spirit of the present invention and change, in the scope that the claim that all should be encompassed in the present invention is protected.
